Manual activating
of the switch
After manual activating the switch of your machine please observe
the reactions on the screen. Each change of switch must be cleary
displayed.The LED flashes of the reference switch should change the
color from black to red.
The definition of the reference switches has been correctly
determined when the LED is black in unpressed condition and
changes to red in pressed condition.
Depending on the used switch (NO contact – NC contact) the
switching logic may be misapplicated, i.e. red colored with the
unpressed switch and black colored with the pressed switch. If this is
the case, a change of the switching logic of the reference switch by
parameter is required.

switching logic
Please carry out the following steps :
1. Open parameter dialog box parameter-machine-signals
2. Select the corresponding reference switch in left-hand window
3. Select the inverted entry in the drop-down menu below and accept
the setting, e.g. change from LPT1 PIN 10 to LPT1 PIN10 INV
4. Save the latest setting and recheck by function SIGNAL TEST
